Yes, you'll need to reference the buttons that you want to pass into the method.

First one is presumably a field(depend on where it is declared), the other one is a property.

Hey guys! I was following the create with code begginer series by unity, I am in Unit 3, in the game the player avoids obstacles running through an endless forest. So obviously the background is supposed to be moving and the obstacle moving and the player stays still and jumps to avoid the obstacles. But in the scripts when I try to call the game Over function to stop the background and the obstacle the player movements Instead Of move left script the player stops jumping and the obstacle and the background keep on moving. pls help. Here are the scripts and the videos discord link to the above messages

Hey can you help pls

with the problem

i changed things because nothing worked

[teal viper]

Mmm... Not exactly what I meant. Don't you have this script on each of the buttons?

[frigid flume]

yes

i have the script on all the buttons

[teal viper]

I'm waiting for you to share the code.

[frigid flume]

each button calls a different function

Then you only need one field for the button on the script

Good morning, I'm finishing my first game. But I'm stuck on something that should be simple but I don't know how to do it. my boss summons these demons. However, if you die and try to press restart the game crashes, from what I think, it's because the demons are trying to follow the player, but the player is dead and has nothing to follow. How do I not have any more summons when the player dies? I will send the link to the codes below. demon controle; https://paste.ofcode.org/Wf8QGE6PrVX5AFQNX9ufNP player; https://paste.ofcode.org/RDJn7EBygswTGacKTiaxgQ boss; https://paste.ofcode.org/r5fYms2KqPpKb3KdNSqpfz

[covert matrix]

i currently have functions that saves a score to an inputted id

    {
        string studentID = PlayerPrefs.GetString("studentID", "");
        
        // Save total score
        string totalScoreKey = $"TotalScore_{studentID}";
        PlayerPrefs.SetInt(totalScoreKey, playerScore);

        PlayerPrefs.Save();

and displays it in a different scene when the id searched for matches a saved inputted id

string totalScoreKey = $"TotalScore_{studentID}";
int totalScore = PlayerPrefs.GetInt(totalScoreKey, 0);```
it currently works but if the same id is inputted multiple times, the data gets overwrriten, but i want to display all attempts scores, how do i account for that?

Move left

[ruby python]

Having a bit of a moment, but how can I get the current rotation speed of an object? I'm using transform.Rotate to rotate the object.

[teal viper]

Something like this:

Object with script and button 1
Object with script and button 2
Object with script and button 3
etc...

Each object would have a script that references the corresponding button. And in the script:

[SerializeField] private Button myButton;
void MethodToCallFromButton()
{
  DoSomethingWithThisButton(myButton, someBool);
}

Makes sense?

[frigid flume]

a bit...

[upbeat stream]

you need to instead of saving an int, serialize it as a json object and save it as a string. then when you read the playerscore you deserialize it to your json class and read the scores, if that makes sense?
that way you can easily and readibly create a list of previous score attempts

[frigid flume]

i create 7 emptyobjects, i attach my script to them, and i attach a different button to them ?

[teal viper]

If you look at your second video carefully, you'll notice that isOnGround stays false. That must be why you can't jump anymore.

[teal viper]

Assuming you want 7 different buttons, yes.

[vale cradle]

i have a really dumb question but i want to know how to select the frames from animation like this?

[frigid flume]

the part i don't get is how to i define the action each button is performing

[viscid needle]

but the guys code is same as mine, the thing does it automatically with code

[covert matrix]

does this work if i only want to display one score at a time, then use buttons to see previous/next attempt scores?

[teal viper]

Assign each object's script and their method to the corresponding button.🤷‍♂️

[teal viper]

Share a link to "the guy's code"

[frigid flume]

is what call a method ModificationCase() for example ?

[upbeat stream]

it should yeah, this is just so you can save and load the data. you would need to cache the data somewhere if you wanted to repeatedly read it, but thats up to your implementation 🙂

[vale cradle]

anyone?

[covert matrix]

thank you

[hexed terrace]

doesn't sound liek a code question? delete and ask in #🏃┃animation

[upbeat stream]

np. just read up on json serialize/deserialize, then you can save larger data sets in playerprefs easily. might have to clear your prefs if you change the structure of the class though

[vale cradle]

i did but it's dead i just want to know what the shortcut key is please

[hexed terrace]

actually pass in a list when you call the method

[teal viper]

I really don't understand what you're saying. Can you translate what you're saying from your native language to english in google translate?

[vale cradle]

i mean if you know then tell me

[frigid flume]

is this a method

i call that a function but maybe it's the same thing

[teal viper]

What's the same thing?

[frigid flume]

method and function

[upbeat stream]

he's asking if Methods and Functions are the same thing

[frigid flume]

or is method a line of code like Debug.LOg

[teal viper]

Read my example that I shared earlier. I even named the method such that it makes sense:
#💻┃code-beginner message

[teal viper]

Oh, are you asking what a method is?

A method is the same thing as a function.

[frigid flume]

ok thanks x)

[cosmic dagger]

yes, they are the same . . .

[frigid flume]

so i create a different method for each button right ?

[teal viper]

Please use puncutation, because it's not even clear wether you're asking a question

[teal viper]

No

[frigid flume]

sorry

[cosmic dagger]

@frigid flume the be politically correct: the difference is, a method is a function associated with a type (in this case, a class) . . .

[frigid flume]

ok thanks

i am understanding so slowly

[teal viper]

button1 on object1 => Script on object1 Method() => Method(parameters referenced in this script)

button2 on object2 => Script on object2 Method() => Method(parameters referenced in this script)

button3 on object3 => Script on object3 Method() => Method(parameters referenced in this script)

Makes sense?

[frigid flume]

i'll try and show you

[frigid flume]

i am supposed to have 7 emptyobjects, and only one script right and one method right ?

Right

i just don't get how i can define which button uses which bool

[rare basin]

what xd

[bold bone]

Performance question

I need to use collision.gameObject.transform.position several times in my code

Would it be more efficient, creating a Vector3 variable inside OnCollisionEnter, to store collision.gameObject.transform.position
And then simply referencing it

[teal viper]

Well, define the bool in the inspector as well.
Make it a serialized field

[tall vortex]

idk what is called or is it modules?

[rare basin]

just read it

and see what you need

if you want android support

then use it aswel

what's hard about it?

[tall vortex]

idk i wanna know if like any of that stuff is like good to have

[frigid flume]

it has to be loaded from Json

[teal viper]

Then load it from json and pass into the method.

You should probably serialize them as an array of bools. You know arrays, right?

[frigid flume]

yes but never used

for now it's good :)

[cosmic dagger]

position is a struct; every time the value changes, you must get/retrieve the updated value. reference the transform and use the reference throughout the class, though, i would store the position in a variable at the beginning of any method(s) and assign the final position back to transform.position . . .

[teal viper]

If you have an array of bools, you just need to do:

Modificationcase(button, boolsArray[myIndex]);

And define the index in a serialized field.

[bold bone]

thx a lot,
by the way, would you recommend declaring the varable inside OnCollisionEnter, or main?

[cosmic dagger]

main? 🤔

[bold bone]

i mean right below the main class, where you have all the serialized fields

sorry for wrong terminology

[teal viper]

Class variable(field) vs local variable

[cosmic dagger]

whichever method you access transform.position multiple times, store a local variable of the position, then update it at the end of the method . . .

if you use the collided transform in multiple methods, then yes, i would create a class variable for the collided GameObject's transform . . .

you can assign it in OnCollisionEnter . . .

[bold bone]

yeah thats what i mean, would it make a difference if the variable is global or local? (i will only use it inside OnCollisionEnter)
since OnCollisionMethod will be called pretty often i would need to be often creating new Vector 3 variables, which may cause more garbage collection
correct me if im wrong

[frigid flume]

i'm not understanding how to do that

[bold bone]

or would i still need to be creating new Vector3 anyways, since every collision will have a different position

[teal viper]

If you need to persist the value, between the calls, then it should be a class field. If it's a local variable, it's destroyed as soon as it goes out of scope(when the method it is declared in returns)

[teal viper]

I shared a code example in one of the next messages.

[frigid flume]

it helped me but i don't understand the json bool part

[cosmic dagger]

if the variable only exist within the one method, there is no reason to store it in a class scope . . .

[teal viper]

What part exactly? You deserialize your json into an array of bools. Then just use an index to access the bool you're interested in.

[hollow zenith]

Sprite position:
x: -5.68
y: 2.47

Parent position:
x: 1.78
y: -1.09

when I get sprite game object position gameobject.transform.position I get:

x: 3.54
y: 0.88

Any ideas? I am trying to convert sprite position into world position(so I can position some UI elements)

Those numbers dont seem to match, localPosition gives better results but its still off.

[wintry quarry]

Where are these numbers coming from?

[hollow zenith]

Sprite has scale of 5 tho if that matters?

[wintry quarry]

what kind of objects are these?

[hollow zenith]

From regular objects, not UI

[wintry quarry]

ok and these numbers came from?

Show the code

and show the scene and what you are confused about

[hollow zenith]

https://i.gyazo.com/d2b7180ea1a8213e343dcd6290316562.png

[wintry quarry]

what object is that?

No context here

[hollow zenith]

I want to get this number into UI so I can show UI on top of the character sprite.

[polar acorn]

The inspector shows local position, relative to it's parent

[wintry quarry]

which number?

[wintry quarry]

the one in the inspector here is localPosition

.position is world space position

[polar acorn]

https://docs.unity3d.com/ScriptReference/Camera.WorldToScreenPoint.html

[hollow zenith]

Yes, I tried to calculate normal position using parent offset and the math doesnt add up

[wintry quarry]

what do you mean by "normal position"

[hollow zenith]

localposition - parent I guess

[wintry quarry]

if you want the world space position of a GameObject that's just Transform.position

[frigid flume]

if a make an array of bool, its a list of "true" or "false" with no names right ? just a number associated ?

[hollow zenith]

oh

[polar acorn]

You don't need to calculate "normal position" that's just .position

[teal viper]

Yes.

[hollow zenith]

So there is no need to do

        Camera.main.WorldToScreenPoint(startPos);

If I get .postion

[frigid flume]

wouldn't that be tricky when i'll have more than 7 buttons ?

accross different scenes

[teal viper]

No. It would be convenient.

It would be tricky if you had to hardcode every bool(like you do now)

[polar acorn]

The entire point of using a collection is because you can expand it

[hollow zenith]

Vector3 targetPosition = CharacterAnimator.gameObject.transform.position;
Camera.main.WorldToScreenPoint(targetPosition); // When I use this Vector to create UI it appears at an offset

ok found the issue

I was using localPosition on UI

[teal viper]

At this point I suggest going through C# basics and unity !learn beginner pathways:

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[hollow zenith]

        transform.position = Camera.main.WorldToScreenPoint(startPos);

This works so far, I knew something was up since it worked earlier, but I was messing up with the code and things didnt work anymore 😄

[frigid flume]

what i don't understand is to define an array using already existing bools without modifying their values

[teal viper]

You do modify them. Either load from json or set via code.

You can do whatever you like if you code it

Setting manually in the inspector is an option to, although it becomes unfeasible very fast.

[icy junco]

anyone who canhelp me with some photon pun bug?

[dapper egret]

Photon are you sure you want to go that route?

[icy junco]

wdym?

[hollow zenith]

        transform.position = Camera.main.WorldToScreenPoint(startPos);
        Vector3 currentPos = transform.position;

        float randomX = startPos.x + Random.Range(-0.2f, 0.2f);
        transform.position = new Vector3(currentPos.x + randomX, currentPos.y, currentPos.z);

Anyone would change anything in this code? Am I doing it right?
I cant seem to find a better way to change x or y of a transform without having to do new Vector or writing a long line of code.

[dapper egret]

As far as i am aware you pay quite a bit for ccu for the dedi servers

[icy junco]

yeah i am just uding free version

what would be a better option ?

[dapper egret]

You can always try unitys networking or even go with fishnet if you want

[icy junco]

allright i will look into that

i also have question for you because you seem to know a bit around server side, is it diffucult to setup your own dedicted server for a game using like an old pc or anything like that ?

[dapper egret]

Not at all,you can always do peer 2 peer througj a relay or go through the pure dedi server one,plently of free online options available

[teal viper]

The main issue is setting up your network to allow connections from outside. Most home internet providers make it difficult due to dynamic IP and other issues.

[icy junco]

but its possible to do if you watch some tutorials

[teal viper]

To a degree. Not something for production where you expect hundreds of people to connect to the server.

You'd also need a way to share the ip address of the server with the users if it's a dynamic ip.

[icy junco]

yeah but like a small server for like my friends?

[frigid flume]

how do i define which index of the array has to be used when button's clicked

[teal viper]

Yeah, should be possible.

[icy junco]

thx

[teal viper]

Define that in the script that comes with the button. Or pass it from the button itself.

[frigid flume]

i got there https://hatebin.com/rmcrdcghan

[teal viper]

No clue what's going on in that code. Your button method doesn't seem to do anything. And you're not passing a bool from an array into it.

[frigid flume]

for the moments it's useless

[frigid flume]

there is no more bool only a bool array

what i tried to do is to assign an int to each emptyobject so it's used to pick the bool from the array

[teal viper]

Yep, that's correct, but you're not using it in the method to be called from the button.

[frigid flume]

https://hatebin.com/daowprupld

thanks a lot for your help and sorry for the dumbbeing

[worthy merlin]

   {
       SceneManager.LoadScene(SceneManager.GetActiveScene().name);
       highScore = PlayerPrefs.GetInt("highScore");
       Debug.Log(highScore);
       if (highScore < 0)
       {
           Debug.Log("High Score is below 0!");
           highScoreText.text = "No Scores Currently";
       }
       if (highScore > 0)
       {
           Debug.Log("High Score is above 0!");
           highScoreText.text = "High Score: " + highScore.ToString();
       }
   }

All of this code is working, but for some reason the highScoreText.text is resetting to the default value of No Scores Currently despite no other code interacting with it in the program. Any idea why its doing this? Also highScoreText is a TextMeshPro if that helps.

[keen dew]

highScoreText in this code refers to the field in the old instance of the scene, not the new scene

[spiral narwhal]

Restart Game should do nothing else than loading the scene

That's bound to lead to bugs

[worthy merlin]

How would I go about changing this?

[keen dew]

Put the code that prints the high score into a Start method of some object in the scene

[worthy merlin]

Gotcha

[spiral narwhal]

Btw I recommend setting up your IDE to show you the compilation errors

And some good starter C# tutorials are pinned

[keen dew]

[slender cargo]

How would you recommend that I save a pre-fabs position so when I quit and reload my game, they are in the same position with the same information.

[keen dew]

[spiral narwhal]

You will have to serialise that object

Yes I know. Just like I said, take a look at the basics of C# first

Use your words to describe what the code is FOR. Right now, as they said, it is nonesense. It is completely wrong in many ways. It is impossible to know even what you are ATTEMPTING to do, so you need to explain before we can help.
Sorry

Oh, I see you DID make one small change. It is not enough to fix it, bit it is a step in the right direction

JsonUtility is useful for serialising game saves

[strong wren]

I wouldn't recommend using PlayerPrefs for game saves either. Saving is basically collecting the data you want to save, running it through some serializer library and dumping it to a file

[slender cargo]

I'll take a look

[spiral narwhal]

Give us the exception stack

[burnt vapor]

As soon as it stops working and returns no data on serialization consider using Newtonsoft instead. JsonUtility is very old and has a ton of limitations which prevents it from working correctly.

[spiral narwhal]

Basically it means somewhere you are using the access operator ., its value is null. Since it doesn't have a value, you can't access anything

What

[stoic ridge]

ok

[slender cargo]

Also would you recommend I have a master save script, or have this on each of the major scripts?

[spiral narwhal]

I would create a FileManager to store all variables you need to store, and provide access to them to other classes

[slender cargo]

So how would I do this for Pre-fabs?

Would you create some sort of loop that gets all the pre-fabs, and sets them all as seperate data sets, then when loading I can just re-instantiate them

I could get all the pre-fabs, add them to an array, then go through the length of the array saving them?

[craggy laurel]

I have a script that basically rotates cards, moving the leftmost to the right and all others one position ot the left. I get huge GC Collection Spikes when I call SortCards(). Can someone tell me why?

I was thinking it might be related to a big amount of new Colors being generated in MakeCardAppear / Disappear?

[rich adder]

Profiler

[olive heron]

starting too many coroutines, at first glance

[frigid flume]

hey, do you know why is that happening ? it's like only one bool is saved...
the code : https://hatebin.com/lqzvqftutb
the problem : https://youtu.be/44qBRIKAYQU (the button is supposed to be green when bool is true, and red when bool is false. it also change color on click (the bool changes too).

[craggy laurel]

Do you want another screenshot of the Profiler?

[polar acorn]

That's a whole lot of GetComponent calls. You're spawning multiple coroutines, that each spawn multiple coroutines, that each call GetComponent multiple times

[rich adder]

have you looked at the profiler when you run the function to confirm?

[slender cargo]

Would this be a good way of saving pre-fabs, if so, how should I go abouts doing?

[swift crag]

I don't know what you mean by "saving" the prefabs

[polar acorn]

Why all the finds just drag them in

[swift crag]

What are you trying to accomplish here?

[keen dew]

That would only save objects with Legendary tags. Also you're not saving prefabs. Any object on the scene is no longer a prefab

[slender cargo]

Well they all hold information in which I need to save such as level, tag, and other variables

[swift crag]

But they're prefabs. They're already..."saved"

[polar acorn]

Still have no idea what you mean by saving them

[swift crag]

they're assets in your project

[keen dew]

Based on the earlier questions, they're just trying to implement a bog standard save/restore system

[slender cargo]

Right so, My breeding script instantiates in a new creature which holds a data set. When I reload the scene, I want that instantiated pre-fab to re-instantiate containing the same info it had

[swift crag]

Are you trying to remember which items your player has?

[keen dew]

them calling the instantiated objects "prefabs" is the confusing part

[polar acorn]

So instantiate the prefab, then change the data on the object you've made

[rich adder]

I doubt it but have you tried commenting out certain parts of code?

[carmine elm]

@burnt vapor can you help me now i done every thing

[swift crag]

You will need to serialize the data that you need to remember.

[slender cargo]

This is the info on the pre fab

[swift crag]

It could look like this

[System.Serializiable]
public class EntityData {
  public int level;
  public string name;
}

[craggy laurel]

I have now commented out all coroutines besides MoveCardToPosition. There are 4 cards, means there will be 4 coroutines of MoveCardToPosition running. I still have the same GC Collection issue.

[slender cargo]

What does this allow me to do??

[swift crag]

You'd store the data you want to remember into an instance of EntityData and serialize it with JsonUtility, then write that data to a file.

you could also just store EntityData somewhere and use it later

[slender cargo]

ohh

[swift crag]

You'd then write code that reads EntityData to configure your entity

That's the gist of serialization and deserialization

Turn your runtime objects into data

@small chasm Do NOT send unsolicited DM's to people in this server

[swift crag]

Then turn your data back into runtime objects

[slender cargo]

so each pre-fab can call public EntityData data; then all write their data to that?

[swift crag]

Each instance in your scene would be serialized

public EntityData Save() {
  EntityData data = new();
  data.level = myLevel;
  data.name = myName;
  return data;
}

public void Load(EntityData data) {
  myLevel = data.level;
  myName = data.name;
}

It could look like this.

Or maybe more like

public void Save(EntityData data) {
  data.level = myLevel;
  data.name = myName;
}

public void Load(EntityData data) {
  myLevel = data.level;
  myName = data.name;
}

I do this in my game. Someone else is responsible for creating the EntityData when saving

[polar acorn]

I wonder if it's just the coroutine itself getting GC'd? I'm not sure if you can avoid that and still use coroutines. Other than the GetComponents I don't see anything else that could be taking up a lot of space in memory

GetComponent only thing strikes me weird as well

[carmine elm]

can somone help me

muscagame is null.
avoid .Find at all costs. Its too frail/slow

[slender cargo]

Right so this is for saving it. Then how do I store the data? Little confused

[spiral folio]

can someone good with unity save me from having a mental breakdown

[swift crag]

How much garbage are you generating per frame? Look at the "GC Alloc" column.

[swift crag]

https://docs.unity3d.com/ScriptReference/JsonUtility.html

Create a class that'll hold all of your save data.

[System.Serializable]
public class SaveData {
  public List<EntityInfo>
}

You can then use JsonUtilikty.ToJson to transform this into a string, which you can write to a file

If you don't need to save data between game sessions, you don't need to do this

You can just store your save data anywhere (maybe in your "game controller" class)

1. did you remove the getcomponent calls? they could be allocating frogloads in Editor if component not found
2. have you tried deep profiling? it can't get more clear about allocations than that

[craggy laurel]

1. yes, I removed the MakeCardDisappear / Appear methods altogether.
2. will try that now

[swift crag]

one more important thing: you need to respawn all of those entities, right?

so you'll need to save an ID that you can then use to figure out what to spawn

You could give each prefab its own ID and then make a list of all of your prefabs

[System.Serializiable]
public class EntityData {
  public string identifier;
  public Vector3 position;
  public int level;
  public string name;

your save data might look like this now

Vector3 lookDir = target.position - transform.position;
lookDir = Vector3.ProjectOnPlane(lookDir, transform.right);
Quaternion rot = Quaternion.LookRotation(lookDir, transform.right);
transform.rotation = Quaternion.RotateTowards(transform.rotation, rot, gunSpeed * Time.deltaTime);

Hello, working on a game and I have this code, what I am trying to achieve is to use the RotateTowards() method, but rotate the object only around the X axis, what I did here does not work at all I was just wondering if anyone knows a way to do this :D

[polar acorn]

So you want a rotation about the X axis, being the "pitch" axis in this diagram, right?

[amber nimbus]

Correct

[umbral gazelle]

Does anyone know why I’m getting this error? And sorry it’s a picture and not a screenshot I’m working on a school computer

[languid spire]

learn how to write switch statements

[umbral gazelle]

This work is in another script I have for my bullets and enemy’s so I’m wondering why it’s not working here. My enemy and bullets die on contact but I want my player to lose health

[languid spire]

big doubt, that code will not even compile

[umbral gazelle]

But it does tho

[languid spire]

also yout !IDE is not configured, do that before asking for more help

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code

[polar acorn]

Still trying to internalize this a bit how this would look. So, if the targit is above and behind the object, you want it to angle up, but not rotate towards the object, right?

Like, if this object is at 0,0,0 and the target is at 0,5,-5 you'd want this object angled up 45 degrees continuing to look forward?

[umbral gazelle]

Because everything was working until I added what I just showed

[polar acorn]

Yes because that's an invalid switch statement

why do you have a switch statement with one condition

[umbral gazelle]

Because it worked for my bullets and enemy’s so I thought it might work for my player. What should I use instead

[polar acorn]

an if statement

[amber nimbus]

It is a tank gun, meaning the turret rotates around the Y axis (Yaw) and the gun only rotates around the X axis (Pitch). The turret is working with the code above (If u replace the transform.right with transform.up)

[keen dew]

Show the other script where it works

[polar acorn]

Okay, so it's rotating about the X and Y axes, that makes a bit more sense.

[umbral gazelle]

These are the working ones

[amber nimbus]

Yes, but the gun object needs to only rotate around X

[umbral gazelle]

Once I changed it to an if statement I just get 3 expected errors

[keen dew]

And you don't see any difference when comparing to the one that doesn't work?

[umbral gazelle]

Well I’m using a break there. But I’m just trying to use my damage script so I don’t know why it wouldn’t work

[polar acorn]

Okay, so the Y rotation is handled by something else, so you just need X for this object

[amber nimbus]

Exactly

[keen dew]

What do you think break does?

[polar acorn]

"Everything's the same except for the thing that makes the code work so why doesn't it work when I remove that"

also don't use switch statements with one case, use an if

[umbral gazelle]

Can you guys actually try and help me instead of criticizing what I’m doing. I get you guys do this for a hobby/job but someone’s who’s new has a hard time learning this stuff and when people just basically call you stupid it makes coding not fun

[keen dew]

We are trying to help you

It was a serious question. If removing break makes the code not work, a) what do you think break does and b) why did you remove it and still expect it to work?

[rich adder]

nowhere did anyone call you stupid...

[umbral gazelle]

Well I get that break breaks that game object but I’m trying to get my take damage to work when the player collided what code would I put?

[rich adder]

You need to go through a basic c# course, thats all

[gaunt ice]

break is a keyword

[shadow zephyr]

break will exit whatever loop or function you’re in

[polar acorn]

Okay hang on I'm trying to think this out, I've gotten halfway through describing it like five different ways before I realize it won't work and deleting it

[shadow zephyr]

it’ll just not execute the rest

[polar acorn]

... "breaks the game object"? What?

[umbral gazelle]

Oh so I was getting it confused with the destroy?

[amber nimbus]

Its all good thanks for putting the effort in you are a real one :D

[umbral gazelle]

I meant destroy I was getting destroy and break confused

[polar acorn]

Please do one of the basic C# courses linked to you. You need to understand the words people are telling you in order to receive help

[umbral gazelle]

Alright but can you tell me why I’m getting this expected error?

[polar acorn]

What do you mean "expected error"

[umbral gazelle]

It says that it need a bracket there but if I put one there’s an uneven amount and everything in incorrectly bracketed

[rich adder]

this is hella wrong

Why is there a case with an if statement

why is the case empty

why is any of this

[timber tide]

neat language what is it

[polar acorn]

Okay, I think what you want to do is to use LookAt but with a constructed target point instead of the target's actual position. I'm trying to come up with a formula for getting a point at the same relative height and distance, that's what's giving me some trouble

Can't just get the LookRotation vector and zero out Y and Z, because there's no guarantee the euler angles of it will be in that exact form...

[summer stump]

Looking at the documentation for a switch statement would immediately reveal what is wrong
A configured IDE would immediately point out what is wrong

A configured ide is a requirement to get help here

But ONE issue I will point out is that you have a semicolon at the end of the case line

[modest dust]

I think that's the smallest issue here

[summer stump]

That's why I chose it

[modest dust]

If he doesn't understand what he's doing

[polar acorn]

Okay, I think I have an idea.

Get the vector from this object to the target, target.position - transform.position.
Then, set that vector's X to zero, and the Z to absolute value of Z (this will avoid the turret looking behind itself)
Then you should be able to use LookRotation with that vector, and set this objects .rotation to that Quaternion

i have to press it like evry 3 secons

[carmine elm]

ok thanks

[polar acorn]

You probably want to store the last IPickupable you were interacting with, and then call .Drop on that instead of the object you're currently looking at

assuming interactObj is something in a collision or raycast

[lost anvil]

yeah interactObj is set as a gameobject the raycast touches

[lost anvil]

ill try this

[amber nimbus]

Oh yeah that works great, thanks :D

I have no idea have you came up with that

[lost anvil]

would that require a variable inside IPickupable?

[hidden sleet]

Currently trudging through some code reorginsation to implement something new and I've basically had to go and redo most things in it, it's structure is really not ideal.

[timber tide]

here

[hidden sleet]

I feel like chucking it all in here would be a bit much

[night mural]

maybe there's some particular aspects which are frustrating that you could call out and focus on?

[hidden sleet]

Unless I sort of abstract it into ideas rather than every single line

[cosmic quail]

theres a chance that maybe someone will take a look at it. if u dont post it then theres no chance of that happening at all

[hidden sleet]

I’ll see what I can do

[night mural]

Yep, if you can share the broad strokes that's sometimes enough. Generally though you may struggle to get much useful advice here on something so in-depth (but it depends what you're working with)

[polar acorn]

Honestly me neither that was actually a surprisingly difficult problem

[lost anvil]

would that require a property inside IPickupable?

[meager steeple]

which has the correct syntax highlighting? and why are they slightly different?

[polar acorn]

No, it'd just require whatever object this script is on to keep track of the last IPickupable you interacted with

[polar acorn]

There isn't really a "correct" one since you could always change it but the second one looks like it's got any syntax highlighting at all which is probably better

[lost anvil]

this script is on my player camera does that matter

[meager steeple]

how do you change the syntax highlighting, cuz in all of mine now i have "using" in blue but in a screenshot i took last week its purple and i prefer it that way

[fringe plover]

What the-

[hidden sleet]

Was trying to write it out but I can't find a feasible way to explain it. The way I've done it is rather convoluted and has so many connected parts. Essentially it's an inventory system with three types, but each type has methods that themselves take different types and do different things, and item containers that are also different types. Each of them has a container, and methods to add / remove items, but I've got them all separate, and I don't know what I could do to have them all a bit easier to follow.

I've tried having a superclass they all inherit from, but then if I call .AddItem or whatever on that super, it won't work since the methods are different for each and the types are different for each

[wintry quarry]

it will fail at runtime

[polar acorn]

That compiles. But it's definitely not gonna run

C# won't know that's nonsense until it tries to actually do it

[wintry quarry]

if I call .AddItem or whatever on that super, it won't work since the methods are different for each and the types are different for each
wdym by "won't work"?

What part doesn't work

what are you trying to do that won't work?

[fringe plover]

Did he even send code or smth?

[wintry quarry]

did not send code

[rich adder]

because T is generic and takes any type, doesn't mean the function will work though

shouldn't that at least give you warning being non-component in console

[hidden sleet]

That's the thing, if I go into it i'll be spewing pages upon pages. I'm trying to find an easier way to describe it but I can't really pinpoint it yet. It all stemmed from me wanting to change something but it's just messy at the moment

[fringe plover]

I didnt check

[hidden sleet]

just ignore me for now, I'll try and get something more concrete

[wintry quarry]

Well the details are important. Right now it's pretty vague. At a high level let's say you have three different items. Maybe one is a potion, one is a sword you can equip, one teleports you home. If you are doing an inheritance pattern there should just be an abstract function called Use on the parent class, and each subclass would implement Use in its own way. For example the sword would equip itself to you, the potion would restore health, and the teleporter would teleport you.

that being said inheritance is not always the best architecture

composition is often better

[hidden sleet]

how does that differ?

[wintry quarry]

so an item could instead all just have something like List<Effect> - where Effect is now an interface for example or abstract class, and every item you just loop over all its Effects and apply them

Or Effect is a delegate type

pointing to different functions

[crimson ibex]

Hello, I have been struggling for a week now, to which seems like a simple thing.
In my 3d game, a character will move on a 2d plane and interact with 5-6 unmoveable gameobejcts.
I can not figure out if navmesh agents is best way to move the characater, or handle movements myself .I have tried both and face many problems in both approach . I do not need physics.
Please guide, which is theoritically better .

[wintry quarry]

there could also be other things like giving them a List<UsageConditions> which you loop over to determine if they're currently usable

[wintry quarry]

Your question is too vague

It depends on what you are trying to achieve

and "handle movements myself" could mean almost anything

[fringe plover]

Why not to just combine? Nav mesh is mostly made just for finding path

[crimson ibex]

I agree . When user touch a gameobejct, character will move towards it and "interact"
When user touches an empty space, character will move towards, while finding best path, avoiding gameobejcts.

[rich adder]

sounds like navmesh is perfect then

[crimson ibex]

Collidiers are creating issues. agent becomes jittery after collision , position and rotation keeps on changing 0.0x

[night mural]

you can always use the nav mesh to do pathing and then move along those paths using your own movement in wahtever way you want

[rich adder]

do your obstacles/objects have the Nav obstacle on it? Put it on carve mesh mode

[wintry quarry]

if you need pathfinding you either use navmesh or implement a known pathfiinding algorithm like A*

also is it a grid?

[crimson ibex]

not a grid

[wintry quarry]

NavMesh is probably the simplest way to start

[night mural]

sounds like you should navmesh it up

[crimson ibex]

i do not know carve, i will checkout

[rich adder]

I usually use carve when the obstacles rotate or move, might be overkill but works well for my agents

[rocky canyon]

so like this?

all ur obstacles should be carving empty spacing in the navmesh

he'll automatically find a path around them

[hidden sleet]

If for example I had a StructuresInventory that had AddStructure, and an itemInventory that had AddItem, both inheriting from Inventory, if I were to pass in just Inventory elsewhere, would that not be able to perform either methods from those other two inventories? only the methods from Inventory itself?

[polar ravine]

How do I can use the Collision2D variable of OnCollisionExit2D in another method?

[rich adder]

pass the reference

store it in a Collider var or something
or pass it through method params if you need to call it right away

[cosmic quail]

do they even need special methods? also abstract methods exist

[crimson ibex]

yes similar, and simpler. thanks for demo

[polar ravine]

Okayy thanjk you

[hidden sleet]

In this case, yes, since they all would take in different arguments and have different ways of adding them

[crimson ibex]

is it trouble-some to use colliders+rigidbody with navmesh ai ? Can they mix

[rich adder]

depends what you're doing

[night mural]

I would question whether an inventory would really need unique behavior for those aspects, or whether your inventories can be simpler (a list of ids) and the complicated handling happens when the items are actually used or whatever

[crimson ibex]

touch to move and touch to interact, only therse 2, on a mobile 3d game

[rich adder]

not sure why you need rigidbody for that

the navmesh is moving the transform and it conflicts with rigidbody movement,
You can put a locked /kinematic rigidbody for example to push other rigibodies though

Raycast, Overlap, Casts etc.

[buoyant rune]

can someone help me , why is there an error at the set function https://gdl.space/ahayafibim.cs dont understnad what this means

[hidden sleet]

I do sort of have an ID system in some parts. For instance all the items of the 'Processed' type have a database where each item has an ID, but all of the raw items are unique and user generated in a way, so they can't simply be ID'd, if I get what you're saying

[crimson ibex]

Ok. I did try Raycast to find how close the two objects are and decide "interaction". but there are multiple gameobejcts close-by, and may be my maths is wrong, but raycast wld pick wrogn object based on transform.forward

[night mural]

Even if the item is unique, the whole item doesn't need to actually be in the inventory -- the inventory could still just contain the id and then the items contain their functionality. That way your inventories are dumb and only the items are smart

[rich adder]

you are trying to set on a prop that is private

you can only set it from inside this class
also sometimes raycast maybe too thin, there are other methods like boxcast, spherecast etc

[rich adder]

maybe your forward was wrong, could be many things. Best way is to just debug instead

[night mural]

Your items should probably exist somewhere on their own and be interacted with directly. The only thing an inventory is is a list of item ids, which you can get one of, resolve to the item, and do stuff with.

[crimson ibex]

Thank you everyone, @rich adder , I will attempt as suggested .

[buoyant rune]

so is the solution to make it public?

[hidden sleet]

Makes sense, but in this case that'll be an ever expanding list of IDs

[night mural]

if that's what you need

[rich adder]

why do you want to set it from outside ?

[night mural]

sounds like maybe that's not an inventory though, since inventories tend to be limited in space

maybe you're doing something more specific and complex but you'd need to explain that

[cosmic quail]

cant you make a single Inventory class and then do Inventory<Structure> and Inventory<Item> or something

[rich adder]

just do
public bool isMoving => _isMoving
if you want to read it from outside but private set, and use _isMoving to set it

also this should be
_isMoving = inputMovement != Vector2.zero
not ==

[night mural]

generics are useful if you have different things which are handled similarly, whereas this is a case of different things which are being handled differently (but i posit that they don't need to be)

[buoyant rune]

but my game is 2d so shouldnt it be vector2?

[rich adder]

yes use vector2 because its inputs

nothing to do if game is 3D or not

[hidden sleet]

If I can find a way to simplify it then I'd love to. But since inputs into the game come from photos taken by the user, which then acts as an item, I don't know how that could incorporate an id system when there isn't any knowledge of what that item could be beforehand

[rich adder]

Unity uses both interchangeably

[cosmic quail]

true they should be handled the same way cause both are inventories, just with different types of items

[buoyant rune]

ohh ok thanks

[cosmic quail]

whats the id system needed for?

[hidden sleet]

Well I was just going by what Prakkus mentioned. But my understanding is just that an inventory could hold just a number which then refers to an item elsewhere

[cosmic quail]

the inventory can hold the item itself, and you can create 2 instances of this Inventory class, one contains structures and the other contains items
Inventory<Item> iteminventory = new Inventory<Item>();
what do you think about this

[night mural]

i'm not sure i understand, cause no matter what the user gives you, you probably want to build that into something your game will use, which you will have full control over and can id or reference however you want

[naive lion]

Hey guys
Using timescale to pause game but the camera still rotates during pause
Not through input, but through momentum, so if I pause before I do a mouse swing, it will still rotate
I am using Cinemachine, anyone got any tips as to what I can look for to solve this

[hidden sleet]

In that case I'm probably the one who isn't following properly

[cosmic quail]

Inventory<Item> iteminventory = new Inventory<Item>();
Inventory<Structure> structureinventory = new Inventory<Structure>();

there's your two inventories and they both use the same class, named Inventory

and both use the same method for adding or retrieving items, just with a different type

by using T

aka generics

[hidden sleet]

Haven't used them all to much. Some people have recommended me not to but I'm not 100% sure on their best use cases and implementations

I'm definitely going to try and draw up some diagrams later

[rich adder]

reset the values to 0 when game is paused

timescale only affects things that depend on it

[cosmic quail]

heres a unity tutorial on them https://learn.unity.com/tutorial/generics#5c8923c5edbc2a113b6bc335

and u can have a method like this in your Inventory class:

public class Inventory <T>
{
    List<T> items;

    public void AddItem(T item)
    {
        items.Add(item);
    }
}

and any things specific to structures or items you handle in their own class

[naive lion]

got it o>

fixed

[hidden sleet]

Can you have it so that you can perform a specific set of tasks depending on the type of the input?

[dusky dirge]

so i have an issue where, when my character runs in a straight line they randomly stop, kinda budge around on the y position, despite the ground being entirely flat. im using a box collider with unity3d (my 2.5D game) and im curious how i can stop this?

[summer stump]

Yes. You can do anything. C# is turing complete

That is also... the most basic thing you do with Input
Do tasks based on type of input describes all user interaction essentially

[wintry quarry]

what is the ground made of

[dusky dirge]

i used a tilemap, using box prefabs with materials on them

[wintry quarry]

so separate colliders?

[dusky dirge]

indeed

[wintry quarry]

the issue is the edges between the colliders. Use this to merge them into one big collider https://docs.unity3d.com/Manual/class-CompositeCollider2D.html

[cosmic quail]

if you want then this is possible:

if (T is Structure) {

}
else if (T is Item) {

}

[dusky dirge]

this'd work for my 3d cubes collision?

[wintry quarry]

kinda defeats the point i think

why not just use virtual methods

[wintry quarry]

3d cubes? No I thought you were using 2D colliders since you mentioned tilemap

[dusky dirge]

oh no mb

[wintry quarry]

Is there a reason you need 3D physics?

[cosmic quail]

i was thinking that as well but if he doesnt want to inherit his structure and item from the same base. do interfaces work here?

[wintry quarry]

You could use 2d physics

[dusky dirge]

ouhh uhhh

idk

i just like it this way

[eternal needle]

Interface or abstract class would be better here yea. You would simply just call 1 method, and each class would implement it as they want

[rich adder]

are you using character controller maybe play around with skin width @dusky dirge

[wintry quarry]

3D physics doesn't have as good of a solution for this problem

you might have to use a mesh collider

and potentially generate the mesh dynamically

[cosmic quail]

yeah i would definitely use an interface here. i didnt say it because i was unsure if you could use these here

interface called IInventoryItem and put it on both your Structure and Item classes. @hidden sleet thats probably the best code you will have if you do it this way

then you need zero if's as well to check their type. cause you just call the interface's methods

[pallid nymph]

(generally for items I think composition > inheritance... but I don't know much about the discussion at hand 😄 )

[dusky dirge]

i looked at night 5 AM and saw nothing, went to bed, just checked now and yes i did.

it works now, thanks for yalls help

[cosmic quail]

idk these terms, whats the difference between these two? 😅

[hidden sleet]

Still trying to wrap my head around how it is different to inheritance. It was brought up earlier but it's the first I've heard of it

[cosmic quail]

inheritance is abstract class and composition is interface? or what do you mean

[pallid nymph]

inheritance is a hierarchy of classes

problem is that at some point you need something to be both a StackableItem and a SomethingEleseableItem (Weapon or something 🤷‍♂️ )

[rocky canyon]

why not bolf?

[pallid nymph]

composition is... you have a single Item class, and it has different components that handle different aspects... you add Stackable component and that handles the stacking aspect, you can put it on an item that has the Weapon component, Damage component, Whatever component

[eternal needle]

Interfaces might make things awkward. With interfaces or abstract class, you inherit some functionality. Anything that has this component will have to use that function. With composition, you just attach stuff that does what you want. If you dont want it, dont attach it.

[rocky canyon]

public class SampleScript : MonoBehaviour, IStackable, ISomethingElseable

[wintry quarry]

Unity's GameObject/Component architecture is a composition architecture.

You don't have subclasses of GameObject

you just attach different components to make it do stuff

[pallid nymph]

it does tend to be both, but usually it's a shallow hierarchy like interface + a few implementations right underneath it on one level, and those are then composed

[rocky canyon]

i tend to use composition

altho... my inspector does get cluttered

ngl

[pallid nymph]

yeah, I made a component that searches in the fields in all components on the current GO 😄

[rocky canyon]

there needs to be more resources on the aspect of designing a fleshed out gameobject

i feel i did 100 uturns / circles when i first started learning to combine scripts

still do.

[minor saddle]

I'm pretty new to Unity, I'm hiding buttons once they're clicked, is there a more efficient way to do this? I got so many buttons, I'm getting confused.

[night mural]

it's because the unity architecture is silly and untenable beyond little prototypes and setting up an alternative is a lot of work

or a lot of work to make tenable

[rocky canyon]

thats how i still do it.. disable buttons / make them un-interactable .. if i can i'll group buttons in empty gameobjects so can i disable them in bulk

[rocky canyon]

what would be a unsilly alternative?

whats silly about it? just wondering

[minor saddle]

Ahh ok thanks. I'll carry on then

[rocky canyon]

if u need to dont be afraid to scratch out notes / about ur buttons on piece of paper

to keep urself more organized

[minor saddle]

Yeah I should really do that

[pallid nymph]

I think that's important part of learning and seeing different options... also, in programming in general it's pretty useful to get used to the idea that stuff will need refactoring sooner or later, and to start recognizing when something is starting to be a problem

[night mural]

everything is public...it's a world where any object can talk directly to any piece of any other object from anywhere

we need rules, people

we live in a society

[rocky canyon]

lol, ohh that happens organically.. i havent figured out how to catch it before hand.. but theres always that moment when u stare at ur codebase.. and are like: "well f***, this isnt gonna work"

then u put it in reverse 😄

[rocky canyon]

ahh i see

[pallid nymph]

then again, there's ECS, which many people will tell you "it's the future and the one true way of doing game dev", and there all data is public

[rocky canyon]

🔥 BURN

[night mural]

Bobby explains a lot of the problems well here (timestamped) https://youtu.be/jjEsB611kxs?t=562

[rocky canyon]

is that ECS related? or general unity

or General Game Engines

[night mural]

the whole video is an overview of the various ways in which engines tend to model entities (including ecs) and some of the pros/cons of each one

[rocky canyon]

ahh okay. i'll give it a bookmark 👍

[night mural]

first he talks about the unity/unreal/etc model, then ecs, then his own opinions on what a good hybrid looks like (but the part i linked is about the unity style)

[rocky canyon]

im on my 2nd year of learning Unity.. and ECS stil feels over the horizon for me

i feel like u need a CS degree to understand how to use ECS

[pallid nymph]

one might say ECS is more organized and simpler

[hidden sleet]

How can I find where this event that I've invoked actually does something? OnItemRemoved?.Invoke();

[pallid nymph]

(Disclaimer: I've not done much ECS though)

[wintry quarry]

find anywhere that has subscribed to it

[rocky canyon]

use find in ur IDE on OnItemRemoved

look for the subscription ^

usually in awake/ start/ onenable

[hidden sleet]

I tried find references but couldn't spot anything

[rocky canyon]

just use Find

[hidden sleet]

actually let me double check that it's actually being used. Will remove it and see

[wintry quarry]

if nothing is subscribing then it's not doing anything

[summer stump]

I would agree with more organized, but disagree with simpler. Mostly because you lose the ability to use most Unity components directly. It is a lot more complex

I do love it though

[rocky canyon]

   void Awake()
    {
        // Subscribe a method to the event
        OnItemRemoved += HandleItemRemoved;  // here is a subscription.. now u know HandItemRemoved() is one of those methods

[pallid nymph]

That's a fair point. It's my main reason to not use it more.

[summer stump]

Yeah. It will get there, but it's a commitment at this point

[night mural]

you could totally do 'in scene' ecs where your gameobjects are entities and your components are components and you just structure things like an ecs but i've not really tried that, donno if there's some gotchas

[meager steeple]

well i just accidentally deleted visual studio code

fun times

[night mural]

you probably wouldn't get the cache benefits but i'm not sure that matters much and you can learn the pattern

[sage mirage]

Hello, guys! I have a question. I heard about not using public access modifier very often and instead of public modifier to use encapsulation and get access to some fields. How can I do that, for example if I want to see my audio sources or my audio clips in my inspector which modifier to use if not public?

[polar acorn]

Cool now you can get the good one and switch to VS

[summer stump]

It's just the program. Reinstall it and your fine

[buoyant knot]

you usually want to sub in enable, and unsub in OnDisable. Unless you have a good reason

[summer stump]

Or do VS ☝️

[summer stump]

[SerializeField] private
That will allow you to use it in the inspector

[meager steeple]

yeah tried doing it from the microsoft site then i couldnt link it in unity

[buoyant knot]

subbing in Awake makes unsubbing a bit more difficult, since unsubbing in OnDestroy can be problematic as multiple different things might be destroyed or being destroyed

[meager steeple]

so im just gonna download from unity or whatever it is

[sage mirage]

Yes but with that private field I won't have access to use for example my audio source on other classes?

[summer stump]

Yes correct.
For that you could do a property

[field: SerializeField]
AudioSource source {get; private set;}

[buoyant knot]

i very rarely make public fields. I very frequently make public getters (with private setters)

public setters or public fields is bad juju, since you make it possible for random classes to fuck with your variables in ways you don’t have complete control over within that class that holds it

there is a time and place for them, but it is more like driving without a seatbelt

i almost exclusively allow external modification to fields via a few controlled public methods

[sage mirage]

Yes but if I have to make a lot of fields public, I have to make for every that field a property?

[buoyant knot]

you never have to make a lot of a fields public

you might need to make some fields public, rarely

the majority of my fields are defined as auto properties

[low path]

i think public setters can be ok since what they do is controlled by code. public variables accessible from outside a class are pretty hard to justy though

[buoyant knot]

private int x;
[SerializeField] private int y;
[field: SerializeField] public int z {get; private set;}

these are the bread and butter patterns

[summer stump]

You mean where the setter is fully defined?
Because I think they meant just set;

[low path]

yeah i mean public set, public get essentially just gives you a public variable

but public setters that are defined are commonly used

[pallid nymph]

my main rule is that stuff should be set in as few places as possible... unless something is a generic stand-alone parameter 🤔

[buoyant knot]

public setters are very prone to abuse. Let the class that holds the variable be responsible to managing its variables, so it knows how to update anything that needs to happen

[pallid nymph]

that's kinda what a setter is 🤷‍♂️

[low path]

yeah that's exactl;y what a setter is

[buoyant knot]

a public setter has to account for basically ANY sort of setting operation that could happen

[summer stump]

Ok, agreed with that then

[buoyant knot]

specific methods only need to worry about one thing

[meager steeple]

i downloaded this thing but its still saying its not there, is there some specific folder i need to put it in?

[rocky canyon]

you tried googling the error?

[meager steeple]

or what is the problem

[rocky canyon]

ive never seen the error tbh

[low path]

a public setter doesn't HAVE to do anything, it's defined in code

you can limit it however you want

[buoyant knot]

once you expose the setter, the setter is now responsible for maintaining order within the class, with respect to changing any internals

[low path]

that's not true, everything inside the class can explicitly refer to the backing field

you can also have properties that aren't explicitly tied to individual backing fields

[buoyant knot]

if mario’s number of lives has a public setter, then that setter better know what to do with a negative number of lives, zero lives, it better invoke SFX, it better tell the UI

but now you can’t separate it easily

[hidden sleet]

So regarding this issue I was having earlier, I've got a better example here. I've got an cs public void UpdateDisplay(RawItemInventory inventory) { method, which will update the elements of a ui to match the inventory contents, but then another one cs public void UpdateDisplay(NewProcessedItemInventory inventory) { for a different inventory type. But since they have different inventory types and slot types, I didn't know how to streamline this cs protected NewProcessedItemInventory ProcInv; public Dictionary<NewDatabaseInvItemSlot, GameObject> invSlotToUiObject = new Dictionary<NewDatabaseInvItemSlot, GameObject>(); , cs protected RawItemInventory Rawinv; public Dictionary<GameObject, NewInventoryItemSlot> UiObjectToInvSlot = new Dictionary<GameObject, NewInventoryItemSlot>(); public Dictionary<NewInventoryItemSlot, GameObject> invSlotToUiObject = new Dictionary<NewInventoryItemSlot, GameObject>();

[low path]

but you already have methods for that?

[buoyant knot]

then why do you need a public setter

[low path]

in the end, a property setter is just syntactic sugar for a method

[buoyant knot]

you no longer have a simple way to just change the number, vs change the number and do all the ancillary stuff

[hidden sleet]

I did try just having a base Inventory class, but then I couldn't use the methods in the sub classes even if I wanted to pass in the subs, because I mostly misunderstood how it worked

[rocky canyon]

public int MyValue { get => _myValue; set { /* sexy */ } }```

[night mural]

is your point basically 'if you are doing something complicated when changing a value, you should probably give that operation a name and make it a method, rather than having a complicated setter which doesn't explain its intent'? cause i think i agree with you there

[buoyant knot]

a lot of my public setters with advanced logic turned into problems, separating responsibilities between specialized methods and calling the public setter

[meager steeple]

right i opened visual studio code once, i closed it and opened again and the syntaxs were different

[low path]

there are lots of classes in unity that use public setters and there are lots of properties that aren't explicitly tied to individual backing fields. you can also have different properties that change the same or multiple backing fields in different ways

this is a common use case

[buoyant knot]

because now you need to go read through code to see if you are supposed to invoke a method, call the setter, or set the backing field

[buoyant knot]

because unity’s source is effectively sealed.

it’s ok to make public setters, but it can very easily and quickly lead to massive issues

[low path]

yeah i mean... you have to be smart about how you're designing and using your classes, sure

but that's always the case

[eternal needle]

You can do literally the same thing with a public setter and method

[low path]

properties definitely have pitfalls

[night mural]

you can't name the public setter though

[low path]

if you're doing too much stuff in them and they're the only way to do that thing, that can be a problem

but i'm not sure i'd say "avoid public setters as a rule"

[pallid nymph]

the one true rule is that you should not follow rules too strictly 😄

[eternal needle]

That has 0 effect on what you can run, yes it makes sense sometimes to use a method but the talk above seemingly was about what a public setter can enforce

[low path]

fwiw i agree with this - changing variable values in a class should be done in the most lightweight way possible and shouldnt' take into consideration every possible way you could change the value of that variable. i definitely think in many/most cases, using methods that modify state in a particular way is advantageous to exposing a heaviweight public setter

[buoyant knot]

the lesson is;
public variables are like public toilets. Everything is fine until someone shits in it.

[rocky canyon]

lol, i try to make everything private and then make things public as i realize i need to

thats my new procedure im trying to make habit

[buoyant knot]

and I try to avoid making setters public

i would rather write a public method that sets for a specific case. And I am still very strict with my public setters

making a getter public when you realize you need to read it is fine imo

[low path]

looking through my code, in my current project, i'm rarely using public setters (or any setters at all) but in a previous project i did, public setters came in very handy. in that case, i was making a runtime inspector for modding a unity game through harmony and the UI controls that I made had a class that modified an underlying runtime value. there, how the setters operated depended on what the underlying runtime value was (determined via reflection), and i found that using a setter that did a few simple checks to determine how to modify the value worked well

[buoyant knot]

because the better you get, the more you restrict the ability to set your variables

[low path]

https://www.youtube.com/watch?v=AL56uQF_0pA

[buoyant knot]

like with this class:

/// <summary>This is affectively an Action, where the inner implementation is
/// a list to allow lots of entries to be added more easily.</summary>
public class BigAction {
    private List<Action> actionList = new();
    /// <summary>Construct big delegate with capacity.</summary>
    public BigAction(int capacity = 16) => actionList = new(capacity);

    public int Count => actionList.Count;
    public void Add(Action action) => actionList.Add(action);
    public void Remove(Action action) => actionList.Remove(action);
    public void Clear() => actionList.Clear();
    /// <summary>Invoke all the actions. Actions can be added to the delegate in the middle, but do not remove.</summary>
    public void Invoke() {
        for (int i = 0; i < actionList.Count; i++) actionList[i].Invoke();
    }
}```

[low path]

been abandoned for 4 years and nobody cares about it but it was a fun project

[buoyant knot]

i could have made that list public, but I did not, so I could make it a lot easier to track and control.

nothing will randomly sort my list. Nothing with randomly assign to some index in the middle, etc. And that is ok

[pallid nymph]

yes, there are many examples where you don't want a public setter 😛

but lets say this class had some parameter that controls how it behaves... it's quite possible you'd just want it to be a public thing 🤷‍♂️

say "ClearListenersOnInvoke" bool (random example 🤷‍♂️ )

[buoyant knot]

as a general rule of thumb, the more things that access an instance of the class, the more you need to restrict access

or very tiny data structure classes probably have a lot of public setters.

[low path]

https://github.com/Hambones82/OniObjectExplorer/blob/master/Components/ControlBase.cs

probably could have used different classes for modifying properties or fields but... this is what i came up with and it worked i guess

set
{
    if (isProperty)
    {
        currentPropertyInfo.SetValue(currentComponent, value, null);
    }
    else if (isField)
    {
        currentFieldInfo.SetValue(currentComponent, value);
    }
    else
    {
        throw new InvalidOperationException("cannot set value where member is neither a field nor a property");
    }
}

but like this worked pretty well...

[queen adder]

Hey guys I have a problem, I'm trying to implement a knock back effect into my game but I noticed that the player movement is overriding it so it doesn't do anything, how can I fix this?

[buoyant knot]

i normally stage movement changes

[summer stump]

A coroutine that disables movement

[buoyant knot]

player movement should happen in normal fixed update

modifiers that have to lead into it have to happen before, and things that modify after need to come after

but since player movement is normally followed by physics sim, whether you modify (via knockback, magnet, etc) in collision callback vs earlier in fixed update, it will all be on the same side

eg the order is still: playermovement => sim => knockback

[queen adder]

Eh I tough of it, but how can I decide when to enable movement again?
I would like it to be enabled again when the player stops getting any velocity from the knockback

[buoyant knot]

are you trying to block playermovement entirely? or adding a knockback effect on top of the movement

what I described is the latter

[queen adder]

I would rather add the knockback effect on top

[buoyant knot]

ok, then what I said

[summer stump]

Wait until velocity magnitude is under a threshold

[buoyant knot]

make sure knockback happens at a point in time where you are ready for it

[queen adder]

Ehh my english and my coding skills aren't that good so I kinda got lost

[buoyant knot]

1. make sure knockback is always applied before or always after playermovement

you do not want the effects to sometimes come before, or sometimes come after. Whichever you pick, it should always be the same

[queen adder]

Well the issue is that the normal "get axis" does that if I'm not clicking anything then the value is 0 so it sets the player velocity to 0 and completely stops everything

[buoyant knot]

2. avoid setting velocity directly unless you want to override everything that came before

[queen adder]

How do I set it NOT directly?

[buoyant knot]

AddForce or related

[summer stump]

You can set velocity directly, but use the current velocity as part of your calculation

Read, modify, write

[buoyant knot]

if it is a kinematic RB, then you want to do like a += velocity, as opposed to just hard setting velocity to a specific number

[whole idol]

I placed this red thingy directly above. But when I play my game it always skews towards the left a little bit, why?

[queen adder]

Hm okay, i actually tried using addforce but it started working in a weird way so I stopped using it.
I'm gonna try again

[buoyant knot]

example;
my player jump modified rigidbody.velocity = new Vector2(velocity.x, jumpSpeed). So it ignores ALL changes to Y velocity that comes before it

but if you .AddForce or do rb.velocity += new Vector2(0,5);
this just adds movement on top of whatever you have

and if your control stick directly sets rb.velocity = to a specific number, then it is overriding everything. You want to not do that

[queen adder]

Okay but won't adding force countiously for the movement make the player faster and faster?

[buoyant knot]

it depends on what you do

a knockback effect should be an impulse force. Adds to velocity once, and then done

[queen adder]

Okay but I'd need to use add force also for the main movement since I don't want it to override everything

[buoyant knot]

add forces ADDS force to whatever forces are already there

[queen adder]

Well but how would I create a script that makes the player move at always a constant speed, but allows for other forces to work

Because the issue is still that even if I add a force for the knockback the player movement just resets it back to the default movement speed

[whole idol]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class WaypointFollower : MonoBehaviour
{
    [SerializeField] GameObject[] waypoints;
    int currentWaypointIndex = 0;
    [SerializeField] float speed = 1f;
    void Update()
    {
        if (Vector3.Distance(transform.position, waypoints[currentWaypointIndex].transform.position) < .1f)
        {
            currentWaypointIndex++;
            if (currentWaypointIndex >= waypoints.Length)
            {
                currentWaypointIndex = 0;
            }            
        }

        transform.position = Vector3.MoveTowards(transform.position, waypoints[currentWaypointIndex].transform.position, speed * Time.deltaTime);
    }
}

I placed this red thingy directly above. But when I play my game it always skews towards the left a little bit, why?

[slender nymph]

this is kind of contradictory because if the player's input is making it move at a constant speed, then outside forces cannot act upon it because that would change its speed thereby making the input no longer apply a constant speed

but you could instead just not get input for the duration of a knockback to allow the knockback forces to work then after a short duration allow input to start working again which will then override any leftover force from the knockback

of course tuning that timing will be fairly difficult because you want it to last long enough that the knockback takes full effect but not so long that the lack of response to input is noticeable to the player

or another thing you could do, which will be more complicated but likely work better in the long run, would be to create your own wrapper class for a Rigidbody that you interface with instead of the rigidbody. you can then track the amount of force input should provide as well as outside forces then combine that manually and assign the velocity using that combined force. That would give you more granular control over the forces being applied to the body while also letting you keep your input's force at a constant rate

[rocky canyon]

u could keep up with velocity..
construct ur vector before hand and pass it into the rigidbody at the end..
ud have ur movement forces and ur knockback forces..
and u add them right before u pass them into the RB
(this method would allow the knockback to influence the player but u'd still have control)
(for example if u got knocked back.. u would be able to push back using ur movement)
but if u werent holding any controls u'd get the full knockback..
oor u'd have to isolate the vectors and zero out ur movement to allow knockback to be the only force.. if thats what ur looking to do

[supple citrus]

This coroutine isn't working

What did i do wrong

[slender nymph]

coroutines do not delay the code they are called from

they only delay what is inside of them

[supple citrus]

so i just put both code lines changing the text inside of the coroutine?

[slender nymph]

https://unity.huh.how/coroutines/waiting

[polar acorn]

It seems to be working just fine. It's doing absolutely nothing after exactly that amount of time

[snow girder]

how to make scalable positive fire rate

i jus don't get it how to do it without a cap

[shell sorrel]

talking when the fire rate exceeds the framerate?

[supple citrus]

is there a way to do this without needing to pass a parameter?

[snow girder]

well how im doing it is

it waits seconds 60 - firerate

[supple citrus]

This is the only time im going to use this coroutine so it seems kind of useless

[snow girder]

so there's a cap when the fire rate reaches more than 60

[polar acorn]

Instead of using a parameter, don't

[supple citrus]

I swear i did that and it gave an error and now it isnt

Ur magic

[shell sorrel]

you need a loop in the update for that, so you need to figure out how many to shoot in 1 frame, then positon them slightly different within that frame

to figure out how many per frame to do, it will be a calculation based on how many you want to fire per second and delta time

[snow girder]

why position them slightly different

[polar acorn]

Because otherwise all of the bullets spawned "between" frames would just be one big stacked giga-bullet

[shell sorrel]

yeah more or less given the first ones in the frame a head start

[snow girder]

well the weapon that i plan on using is not automatic so i don't think we'll need to worry about it exceeding one frame

[shell sorrel]

then what is the issue then

[polar acorn]

Well, you also wouldn't have to deal with a firing rate being less than one frame

[shell sorrel]

if you are not worried about that problem, its a much more simple problem to solve

[polar acorn]

Honestly I don't think you'd have to deal with it being less than two frames because in order to press the button it first must be released

[shell sorrel]

well that is how UI is handled, but generally shooting is on press not release

[polar acorn]

Yeah but if you press a frame on two consecutive frames, would Unity actually know that's two presses and not a hold across two frames?

[shell sorrel]

but if not worried about multiple per frame, its a simple set a field on shot to how long you want to wait in seconds, and per frame subtract delta time, and dont allow a fire again till its 0 or below

[polar acorn]

Yeah, I'm just pointing out that even if you had zero cooldown you'd still only be able to fire at a rate of one shot per two frames, so there is a cap even without programming one in

[snow girder]

its like 20 minutes till dawn if you get me

or isaac

you can hold the button and it spits out a bullet ever 2 seconds or smth

[polar acorn]

So it is automatic

Why did you say it wasn't

[shell sorrel]

if you want it to require a new press for each shot, but act on the press not the release

[snow girder]

oh wait

[shell sorrel]

just use a bool

[snow girder]

you're right

[shell sorrel]

reset it on release

so on press checks if its aloud to fire, then sets the bool

[polar acorn]

So back to the original solution then

[shell sorrel]

release unsets the bool

[polar acorn]

#💻┃code-beginner message

[snow girder]

yeah i could do that

but i don't want it to be so automatic that it does like

5 buleets in 1 frame

[polar acorn]

Then just don't make them shoot that fast

[snow girder]

i suppose thats a cap then

[shell sorrel]

a timer then

[snow girder]

but how do firerates even work anyways

[shell sorrel]

make a shotDelay field

[snow girder]

have a positive value make another go down

[shell sorrel]

before shotting make sure its 0 or below

when you do make a shot set it to how long you want to wait

subtract deltaTime from it every frame

[polar acorn]

You set a bool when you shoot, check that bool is false before you shoot, and after a period of time, un-set it

[snow girder]

yeah but how do we calculate the period of time

[shell sorrel]

dont evne need the bool

[snow girder]

since there are gonna be items that make the firerate go up

[shell sorrel]

yeah that is fine

[polar acorn]

That's entirely up to you

[snow girder]

and im having trouble figuring that out

[shell sorrel]

you just adjust what you set shotDelay to

guess shotDuration is a better name

[snow girder]

makes sense

[shell sorrel]

dont fire when its above 0

[snow girder]

wait actually

what the hell is a field

[shell sorrel]

when you are aloud to fire, you set it to how long you want to wait

then on update you also do a shotDuration -= Time.deltaTime

[shell sorrel]

a variable that is defined on the class not in the function

[snow girder]

right

okay thanks for your help

[shell sorrel]

so like private float _shotDuration; on your class

[snow girder]

you guys are based

[snow girder]

yeah but how do we calculate that tho

since the firerate is a positive number

and it only goes up

not down

[polar acorn]

I don't know what you mean

[shell sorrel]

you wnat a firerate that is like 5 shots per second

[snow girder]

like it improve the more it goes up

so the faster you shoot the more it is

[shell sorrel]

you just have a shotDuration of 5/60

[polar acorn]

Then you reduce the amount of time between shots

[snow girder]

yeah but how do you calculate that

like how much time should be reduced

[polar acorn]

With - usually

[snow girder]

if it goes up by one

[polar acorn]

But multiplying by a value smaller than one also works

[snow girder]

okay you know whaty

i got this

[shell sorrel]

public class Gun : MonoBehaviour {
    [SerializeField] private float _fireRate = 10f;
    private float _shotDuration;

    private void Update() {
        _shotDuration -= Time.deltaTime;
        if (_shotDuration > 0) return;

        if (Input.GetButton("Fire")) {
            _shotDuration = 1f / _fireRate;
            Fire();
        }
    }

    private void Fire() {
        // todo fire the bullet
    }
}

something like that, untested but gives the gist

[night mural]

what is fireRate? you might have an easier time if you think of it as shotsPerSecond or something like that

[snow girder]

bro i used an Ienumerator 😭 😭 😭

[shell sorrel]

though generally i would not define fireRate like this

like instead of saying 10 shots per second like that and needing to divide

[meager steeple]

I have this code to change the full screen mode to be that of the a toggle isFullscreen

{
  public void SetFullscreen (bool isFullscreen)
    {
        Screen.fullScreen = isFullscreen;
        Debug.Log("Toggled Fullscreen");
    }
}

however when i leave it in windowed, close the game, and then reopen it, it will start the game in windowed, but the toggle is still true

[shell sorrel]

i would say it waits 0.1 seconds between shots and skip that division to convert from firerate to delay

[snow girder]

crap how do i explain this 😭

its gonna sound really stupid but it's like a revolver that you hold down to shoot...

[shell sorrel]

oh so you want the delay to happen after you press the trigger

[snow girder]

you hold down the button and it shoots then waits however long then shoots again without having to release said button

[shell sorrel]

very simlar idea, you just start the countdown after press, then fire wehn its 0

[snow girder]

it stops after you releases

[fading rapids]

how do you reference another float from another script for example, public float sens = 50f;, and in a different script i do if(...) sens = 0;

[noble forum]

hi, may anybody tell me why in my chess game this script summons a queen after promotion correctly (1) but when i tried to change it with giving few options to the players it suddenly stopped working (2) The piece is always black and it spawns always on 1 side of the map, not where the pawn was?

    }
}

Does anyone know what this error is? Everything works well as intented but I just wanna get rid of this error !

[shell sorrel]

well look at line 12

[slender nymph]

and read the error message

[shell sorrel]

its a pretty good and descriptive error message

[polar acorn]

Looks like the variable waypoints of WaypointFollower has not been assigned.
You probably need to assign the waypoints variable of the WaypointFollower script in the inspector

[noble forum]

https://gdl.space/acizifomok.cs working one

[whole idol]

I did assign em

[noble forum]

https://gdl.space/aziyeqotaq.cs not working one

[polar acorn]

Okay so show where you've assigned them

[shell sorrel]

that screenshot shows nothing

[whole idol]

I assigned them on these thingies right here

[polar acorn]

Okay so show that

show where you've assigned them

[whole idol]

oh wait I just realized I didnt assign them

by adding component

[polar acorn]

Almost like you shoulda read the error and did what it said

[whole idol]

I assigned them on the red box named "Enemy"

And then... I assigned 2 way points in the waypoint script inside of that

[shell sorrel]

have to keep in mind, there can be multiple instances of any given script in the scene

and the reported error might not be for all of them

[noble forum]

Anybody knows why?

[whole idol]

so should I just ignore that error ?

[shell sorrel]

no

[whole idol]

sometimes I get errors like this and then later they go away Idk why

[shell sorrel]

figure out why you have the error and resolve it

[polar acorn]

No you should fix it

[whole idol]

what do you mean?

[shell sorrel]

you have more then one WaypointFollower in your scene

make sure waypoints are assigned correctly on all of them

[polar acorn]

You have a bunch of objects assigned here that you're enabling whenever a promotion happens. Why? It's going to activate whatever you dragged in, not spawn a new object

[noble forum]

Those are buttons

It should work like that:

[whole idol]

I did. They are all assigned

[noble forum]

The pawn enters promotion, player get to choose from 4 options as in normal chess via buttons, when he chooses one all other disappear and the selected piece is supposed to go on the tile

[polar acorn]

Search t: WaypointFollower in the hierarchy

[whole idol]

Oh I found it. Thank you

[noble forum]

It spawns the piece and disables the buttons but piece alwais spawn in thhe corner and it is always black, when queen from first script changed colors and were on the same tile as pawn

[whole idol]

floor (4) had one as well. I deleted it. Not sure why im still getting these errors though

[polar acorn]

Did you clear the console and run it again

[summer stump]

Did you clear the errors and ru- ah, too slow

[polar acorn]

Try logging your ___Promote varaibles when you try to promote, as well as what piece is

See what values aren't what you expect them to be

[noble forum]

Well, i see that the type of piece is spawning. It is only black and spawns on a1 so it doesnt read position for some reason

[polar acorn]

It's getting that data from piece, so where are you passing in piece

[noble forum]

Well, piece is a pawn that is destroyed upon promotion

[polar acorn]

which one

[noble forum]

The one that reached promotion

[polar acorn]

Are you sure

did you check

[noble forum]

Yea

[polar acorn]

How did you check?

[whole idol]

Oh yeah. now it's gone. But now that I run it I see something else being weird here with the movement of these enemies. The entire cube has shifted towards the right where In reality they're literally placed right above the green floors and they have the exact same positions and scales so why is it moving like that?

[noble forum]

Few different pawns went, all of them were destroyed on different tiles, then promotion spawning begun

[polar acorn]

Do they actually move or is it just that their starting position isn't where you expect it to be

[polar acorn]

Okay but how does that prove that the piece passed to this function is the right pawn

[noble forum]

It works with 1st script, but for queen only

[whole idol]

Also the waypoints have the same X and Y position

[whole idol]

their starting position is fine.Its when theyre starting to move that they break up

[queen adder]

heyyy

[polar acorn]

How are they moving

[whole idol]

following the waypoints

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class WaypointFollower : MonoBehaviour
{
    [SerializeField] GameObject[] waypoints;
    int currentWaypointIndex = 0;
    [SerializeField] float speed = 1f;
    void Update()
    {
        if (Vector3.Distance(transform.position, waypoints[currentWaypointIndex].transform.position) < .1f)
        {
            currentWaypointIndex++;
            if (currentWaypointIndex >= waypoints.Length)
            {
                currentWaypointIndex = 0;
            }            
        }

        transform.position = Vector3.MoveTowards(transform.position, waypoints[currentWaypointIndex].transform.position, speed * Time.deltaTime);
    }
}

[polar acorn]

Then I would assume you should move the waypoints

[noble forum]

The pawn is destroyed then i get to choose the button, they dissapear and a piece appears. It is black and on a1, so it doesnt reach position of a pawn

[noble forum]

Hello

[polar acorn]

So since the color and position come from piece, you should log what that is so you know what it actually is

[queen adder]

FUCK i got sidetracked and i didnt ask my question

anyways, visual studio doesnt work on linux so what should i use instead of visual studio code

[noble forum]

I just ended a tutorial about this, i thought that team color indicates colot

[noble forum]

Yea, happends a lot

[summer stump]

Check if Rider works I guess.
Those are the big three.

Otherwise it's gonna have to be vim 😂

[polar acorn]

It probably does
